What are Film Capacitors?

Film capacitors, also known as “film capacitors”, “poly film capacitors”, “plastic film capacitors” or “dielectric film capacitors”, are a type of capacitor that uses a thin piece of dielectric material (usually plastic film) as the dielectric layer between two metal plates. The thin film acts as an electrical insulator, separating the two metal plates from each other. When voltage is applied, current flows through the thin film, creating a capacitance effect that stores electrical energy.

The MKP1839510634HQR application field and working principle

The MKP1839510634HQR is a polypropylene film capacitor with an integrated thermistor for temperature compensation and is designed for general electronic use. It is commonly used in audio applications, to provide a more stable frequency response. It can also be used for power supply decoupling, input/output filtering, and noise suppression.The MKP1839510634HQR has a capacitance of 0.068uF (micro Farads) and a rated voltage of 250V. The maximum temperature rating is +85°C, and the rated dielectric strength is 5kV AC.The MKP1839510634HQR works on an RC (resistor capacitor) circuit. When current flows through the capacitor, the dielectric material separates the plates and a capacitance is created. This capacitance stores energy, which is then released when the current changes. As the temperature varies, the capacitance of the capacitor also changes, which affects the overall frequency response. The thermistor compensates for these changes and helps to maintain a more consistent frequency response.

Conclusion

Film capacitors are a type of capacitor that uses a thin piece of dielectric material between two metal plates to create a capacitance effect. The MKP1839510634HQR is a polypropylene film capacitor designed for general electronic use and is commonly used in audio applications to provide a more stable frequency response. It has a capacitance of 0.068uF and a rated voltage of 250V, and features an integrated thermistor to compensate for temperature variations. Its working principle is based on an RC circuit, where the capacitance stores energy and the thermistor maintains a consistent frequency response.
